Motor Sizing Basics Part 4 - Radial Load and Axial Load

Posted by Johann Tang on Mar 31, 2020 7:58:57 PM

Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.

Motor Sizing Basics Part 3: Acceleration Torque (and RMS Torque)

Posted by Johann Tang on Feb 27, 2020 9:05:40 PM

Now that we understand the calculations behind load torque and load inertia, we're two steps closer to motor selection.  You might be wondering why I separated load torque and acceleration torque calculations.  That's because in order to calculate for acceleration torque, load inertia and speed must be calculated first.

Motor Sizing Basics Part 2: Load Inertia

Posted by Johann Tang on Jan 17, 2020 7:51:53 PM

Other than torque or speed, another factor should be considered when sizing motors.

Motor Sizing Basics Part 1: Load Torque

Posted by Johann Tang on Jan 14, 2020 8:14:54 PM

Proper sizing of a motor requires that 3 criteria must be met: torque, load inertia, and speed.  For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.

Introduction to MEXE02 Support Software (VIDEO)

Posted by Johann Tang on Mar 12, 2019 7:30:00 AM

The MEXE02 support software is a universal motion control and monitor software used with many products from Oriental Motor, such as the stepper motor drivers from AZ Series, AR Series, and RK2 Series, or brushless DC motor drivers from BLE2 Series and BX2 Series.  This post is useful for first-time users to gain a quick understanding of the software and what it can do.
